SPECIFICATION forming part of Letters Patent No. 395,834, dated January8, 1889.

Application filed October 13, 1886.

To all whom it may concern.-

Be it known that we, ARTHUR KI'rsON and WILLIAM SMITH HOBBY, both of thecity and county of Philadelphia, and State of Pennsylvania, haveinvented an Improvement in Carbureting-Lamps, of which the following isa specification.

Our invention has reference to gas-fixtures; and it consists in certainimprovements, all IQ of which are fully set forth in the followingspecification, and shown in the accompanying drawings, which formpart'thereof. Heretofore gas-fixtures of this class have been made withan extensive heater for the incoming gas arranged above the flame, whichheater and gas-pipe were exposed to the atmosphere on all sides and thecarbureting-receptacle was located below the gas-burners and detachable,leaving the burners as part of the suspended fixture. It has also beenproposed to provide a gas-fixture with a central heaterpipe having asurrounding case and a carbureting-receptacle above the burners andheated thereby. It has also been proposed to 2 5 suspend shades by meansof expansible clamps, but not in connection with a gas-fixture of thenature hereinafter set out.

Our invention has particular reference to a form of fixture set out inour application,

Serial No. 202,598, filed May 19, 1886, in

which a central gas-pipe is divided longitudi nally into spiral passagesand surrounded by a heat-arresting case, which, while it heats the gasto a constant degree, prevents overheating. In that application the saidconstruction is embodied with the employment of a carbureting-receptacleat the bottom of the gas-supply .pipe and below the gas-burners. Thisapplication is an improvement thereon in the following respects-viz.,the carbureting or enriching receptacle is made with the burners rigidlysecured to it, whereby, whenever the receptacle is removed forreplenishing, the burners must be removed also, and thus theirinspection is naturally insured. Gas-burn ers in fixtures of this classhave a tendency to become clogged by the deposition of the carbonaceousdeposits from the enriched gas, and it is of the utmost im- I serial No.216,127. (No model.)

portance to provide means for the proper inspeotion of said burnersawork which cannot be properly done when the burners are made part of therigid fixture, as has heretofore been the case. The construction mayalso be simplified by making the burners rigid with thecarbureting-vessel. The construction of the heater-case for arrestingthe products of combustion is extremely simple, and yet most desirableand ornamental. The gas-regulating valve is arranged at the top of thegas-pipe and protected from heat by an extended shield, which alsoprotects the gaspipe above the valve from ascending heated products,preventing it acting as a heater in any manner. The shade is held to thefixture by a removable jointed clamp, which encircles the heater-case,and hence may be readily applied to fixtures already erected, and may beadjusted high or low, as desired.

The foregoing improvements enable the fixture to be used with the besteffect and with the least care, is cheap to construct, durable in use,not liableto get out of order, and is highly ornamental in appearance.

In the drawings, Figure 1 is a sectional elevation of a gas-fixtureembodying our invention. Fig. 2 is a plan view of the burners I and carbureting-receptacle removed from the gas-pipe, and Fig. 3 is aperspective view of the adjustable and removable shade-clamp.

A is the central gas-supply pipe, and is connected at the top to thegas-main section B by a valve, C, having an operating-lever, c. Thisgas-pipe A is preferably provided with a spiral or twisted ribbon ofmetal, a, to cause the gas to be divided and insure its being thoroughlycirculated and mixed, whereby it is all uniformly heated to a fixeddegree.

Surrounding the pipeA at the top and resting against the valve C is alarge washer, M, 0 which receives the large circular shield L, the outerpart, Z, flaring upward and throwing off any ascending products ofcombustion or heated air and keeping the gas-pipe above the shield cool.The lower part of this shield re- 5 ceives the upper end of the case K,which forms an annular space, It, around the gaspipe, the top of whichis practically or simultaneously closed. The small leakage at the jointon, or from one or more very small holes, N, in the top of the casing,would be advantageous in very slowly and gradually causing a change inthe heated products in the space 7.". The lower end of the case K iscentered and held up by hell 0, which is preferably of much lessdiameter than the shield ll. This bell has a shoulder, 0, which receivesthe case K and keeps it in place. The upper part of the bell fits snuglyaround the pipe A, and is perforated, as at o, to allow ingress to theheated products ascending from the burners. This bell is held up inplace by a sleeve, '1, which surrounds the pipe A, and which is clampedupward against said hell by the nut l) of the coupling for connectingthe burners and caldmretingwcssel to the gas-pipe A. It will now beobserved that the fixture from I to D is all rigidly clamped together byvalve C and nut l), and yet it may be dismantled when desired forrepairs. This portion of the fixture secured to the building by apermanent joint. y

The carlmreting-vessel II is made of light sheet metal spun into shapeand permanently secured to the coupling-sleeve E. Screwed into the sidesof this piece E and close to the carburetor are the gas-burner pipes G,which radiate from the center and are provided with the burner-tips g.From this it will be seen that there is one large central opening, F,and a series of small lnn-ner-openings from the carburetor. Thiscombined carburetor and burner is detachably secured by thecouplingjoint e with the nut I), and the joint is made gas-tight by apacking-washer, d.

J is a small end section of pipe, which may be screwed into the bottomof the gas-pipe A and project through the opening 11 into thecarburetor, as shown.

By thus making the carburetor rigid with the burners both must beremoved together, thereby enabling the burners to be thoroughlyinspected and cleaned every time it is required to replenish thecarburetor with the carbureting material, which is in practice acrystallized carbon of high volatility. Considerable dit'ficulty hasbeen experienced in attaching shade or shades to fixtures of this class.In some instances shades are not desirable or wanted; but heretofore ithas been necessary to secure the holder for the shade rigidly on thefixture, whether the shade was required or not, as otherwise, it a shadewere required, the entire fixture would have to be taken apart to put ontheholder. In the present construction the globe-holder P is made of twoparts, P, hinged together at p and clamped upon the case K by athumbscrew, 1), which draws the parts P together. These parts of theclamp have the hooked arms I, which fit into the annular groove 8 of theshade or globe S and support it. By this construction the shade maybereadily adjusted high or low, as desired. This clamp may be modified inmany ways, the detail thereof being immaterial to our invention, as theessential feature is an adjustable clamp with a fiXtu re of this class,whereby the shade and its clamp may be put on or taken off a fixturewhen in use. The shade is of such a shape and diameter that it collectsand directs the products of combustion up between the annularspace-formed by the arms of the clamp and shade around the case K to protect it against cold-air currents. The form of coupling between the pipeA and carlmretor may also be modified; hence while we prefer theconstruction shown the details thereof may be varied without de iartingfrom ourinvention.

\Ve do not herein claim the subject-matter claimed in our applicaticm,Serial No. 202,598, tiled May 19, lSSb'.
